Global environmental dangers are among the most profound challenges facing humanity. They currently undermine the quality of life for many and threaten, in the extreme, to compromise the fundamental, organic infrastructure that supports all life on earth. This course introduces students to the sociopolitical dynamics of global environmental affairs. It explores the causes of environmental harm and avenues of effective response. Furthermore, it examines a number of key environmental challenges including species extinction, food and agriculture, and climate change. Its overall aim is to familiarize course participants with the role power plays in the emergence of environmental problems and how power in turn can be wielded in the service of sustainability.
